Based on fossil evidence, how can scientists know what color dinosaurs were? In this TEDEd lesson, Len Bloch shows how making sense of the evidence requires careful examination of the fossil and a good understanding of the physics of light and color.
In this terrific video you'll learn a bit about the microraptor, a four-winged carnivorous dinosaur with iridescent black feathers, as well as the work that scientists do in determining how dinosaurs actually looked.
